Name:limited transitivity

Limiting the ability of information to flow more than a certain
distance (perhaps in hops) from its original source. Examples include
special operating systems that track transitive information flow and limit
it and technologies that can only be shared a few times before losing their
operability.

Complexity: This is not a highly complex area, but there is a tendency for
information to rapidly reach its limit of transitivity and there are
restrictions on the granularity at which control can be done without
producing high mathematical complexity on time and space used to track
transitive flow.
